EFC4630R-TR

Overview

The EFC4630R-TR is an N-channel depletion mode MOSFET manufactured by onsemi. It features a maximum drain-source voltage of 24 V and a continuous drain current rating of 6 A. The device utilizes the EFCP surface-mount package with four pins. Key electrical parameters include a maximum drain-source resistance of 31 mΩ, a gate threshold voltage range from 0.5 V to 1.3 V, and a maximum power dissipation of 1.6 W. It operates at temperatures up to +150 °C.

Feature Summary

• N-channel depletion mode operation for normally-on functionality
• Low on-resistance for efficient power handling
• Compact EFCP surface-mount packaging

Applications

• Power switching circuits requiring normally-on behavior
• Load management in low-voltage systems
• Industrial control interfaces

Procurement Notes

Verify the specific manufacturer datasheet for the EFC4630R-TR to confirm all electrical limits and thermal characteristics before integration. Ensure that the EFCP package dimensions align with the target PCB footprint. Cross-reference the part number with official onsemi documentation to validate availability status and lead times through authorized channels.

Selection Notes

Select this component when a depletion-mode N-channel switch is required for 24 V applications. The 6 A current rating and 31 mΩ resistance suit moderate power loads. Consider the EFCP package size for space-constrained designs. Verify that the depletion mode characteristic matches the circuit logic requirements compared to enhancement-mode alternatives.

Part Context

This component belongs to the family of depletion mode MOSFETs offered by onsemi. These devices are distinct from standard enhancement-mode transistors as they conduct current at zero gate-source voltage. The EFCP package provides a compact solution for surface-mount assembly, suitable for modern electronic designs requiring small form factors.

Replacement Considerations

Check for direct pin-compatible replacements within the same EFCP package. Verify that any substitute maintains the depletion mode characteristic and meets or exceeds the 24 V and 6 A ratings. Consult onsemi documentation for recommended alternative part numbers if this specific variant is discontinued.
